Favorite tag is best tag, futa.
I like it cause when it comes to porn, I almost never give a damn what the guy looks like. I mean in alot of shots the dudes only appearance on the page is the important part, his dick. Otherwise, he isnt important. So with two (or more) girls, I'm much more invested in what everyone's faces is looking like, what they feeling and so on. Bbuutt I was born with a penis, so my feeling of sex kinda orients around my dick feeling. So with futa, I can watch hot girls get off, and actually understand the feeling of at least one of them.
That being said I understand there is controversy to the tag's name. When I hear futa I think chicks with dicks, not saying they are not chicks or they are less of a woman, just they happen to be a girl with a penis (or both) below the belt. Some people may feel connected to the title and not like to be a fetish for anime and I wish there could be some middle ground to land on... but I still really like futa
